  • The uses for laboratory notebooks and best practices
  • Using scientific notation and significant figures
  • Interpreting scientific charts and graphs
  • Comprehending non-textual and textual scientific presentations
  • Measuring data precision and evaluating accuracy
  • Judging data by considering the potential for error
  • Learning the formulas to measure median, mean, and mode

There are many areas of science to cover beyond this chapter about scientific data collection and manipulation.
